The U.S. Coast Guard will hold a public hearing next month as part of its investigation into the sinking of the container ship El Faro. All 33 crew members, including four Mainers, died when the ship sank during Hurricane Joaquin in the Bahamas in October. One of the four Mainers was the ship’s captain, Michael Davidson of Windham. The first phase of the Coast Guard hearing will take place at a convention center in Jacksonville, Florida, Feb.
